SMTs for sure, but I'm a huge, huge fan of cryptocurrency in general. I see massive, global need for us as a species to get away from violence-backed fiat currency. From there is't a matter of figuring out which cryptocurrency is the best form of money (i.e which one is the best ledger). To me, from a technical perspective, STEEM is very high on that list right now, regardless of the other use cases for it in terms of a utility app token.
